But is politics supposed to really be about lies?
the greatest political lies all start with "if I'm elected....."

Most of them meant every word they said during the elections campaign period, but immediately after they are voted into power, they forget all the promises they've made and allow the power they now hold intoxicate them. Many of these politicians are taking advantage of the fact that the people they represent are very easy to be manipulated, they won't learn to keep to their campaign promises as long as the masses do not say NO! to all forms of manipulations and deceit initiated by the politicians and their cohorts. There are still good politicians though, but the corrupt politicians and even the masses won't allow their goodness to be felt.
How is that even possible that they have good intentions and immediately they get into office tgiwr good intention immediately vernishes? From the kind of outrages promises they make during campaign to how much money they are willing to flung out, it's obviously clear that they are just trying to leverage on the vaulnaurability of the masses to secure there votes and end it all at that point.
How possible a politician stand up to his promises is always an interplay of his personal resolve to meeting those promises and the plan of the party he belongs to. Sometimes we blame a particular politician and leave out the platform he contested under. Those political party still have thier own role to play in assisting or frustrating some good effort of politician that have the plan of matching thier words with action.
